[0001] The present application relates to the technical field of starry sky interior parts, and in particular to a starry sky interior part, a vehicle compartment ceiling and a vehicle. Background Art

[0002] With the growing demand for personalized vehicles, the vehicle modification market is booming, and vehicle ceilings featuring starry sky interiors have emerged. These decorative components, installed on vehicle ceilings, create a starry sky-like visual effect by arranging numerous small light sources. These components reflect people's pursuit of a romantic and unique cabin environment. Designing these components to enhance the user experience has become a key topic within the vehicle industry. Utility Model Content

[0003] The embodiments of the present application provide a starry sky interior component, a vehicle compartment ceiling and a vehicle, which are used to solve the problems in the related art that the light source of the starry sky interior component is easily damaged by bumps and the starry sky interior component has a poor luminous effect.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In the first aspect, an embodiment of the present application provides a starry sky interior component, comprising a light source and a fabric layer; the light source comprises a carrier layer, and a light-emitting element array arranged on the carrier layer, the light-emitting element array comprising a plurality of light-emitting elements, and the light-emitting surface of the light-emitting element faces the first side of the carrier layer; the fabric layer is stacked on the first side of the carrier layer, and the fabric layer has a hollow portion at the position corresponding to the light-emitting element, and the hollow portion can allow light emitted by the light-emitting element to pass through.

[0006] The starry sky interior decoration part in the embodiment of the present application is formed by stacking the fabric layers on the light-emitting side of the light source, and the fabric layers have hollow parts at the positions corresponding to the light-emitting elements, so that the light emitted by the light-emitting elements can pass through the fabric layers through the hollow parts, which can ensure the normal light emission of the starry sky interior decoration part, and there is no need to set up optical fibers to guide the light source, thereby simplifying the structure of the starry sky interior decoration part and reducing the cost of the starry sky interior decoration part. At the same time, the fabric layer is arranged on the first side of the bearing layer to cover and protect the light source, preventing the light-emitting elements of the light source from being directly exposed outside the surface of the fabric layer, thus preventing the light-emitting elements from being bumped and damaged, which is beneficial to reducing the maintenance cost of the light source. In addition, each light-emitting element (i.e., light point) of the light-emitting element array is an independent light-emitting unit, and the light-emitting effect of the light-emitting element (such as light color, light brightness and flashing frequency, etc.) can be controlled separately, which is beneficial to improving the light-emitting effect of the starry sky interior decoration part.

[0007] In some embodiments of the first aspect, the hollow portion is a first light-transmitting hole provided through the fabric layer, and the area of ​​the first light-transmitting hole is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to better align with the hollow portion, thereby preventing the fabric layer surrounding the hollow portion from obstructing the light-emitting surface of the light-emitting element.

[0008] In some embodiments of the first aspect, the fabric layer is a textile layer, and the hollow portion is a structural hole of the fabric layer. This arrangement eliminates the need to additionally provide a hollow portion on the fabric layer, thereby simplifying the manufacturing process.

[0009] In some embodiments of the first aspect, the hollow portion is a first micropore array comprising a plurality of first micropores extending through the fabric layer, each having a diameter of less than or equal to 0.1 mm. This arrangement ensures normal light transmission while effectively preventing larger objects from contacting or colliding with the light-emitting element, thereby better protecting the light-emitting element and minimizing the impact of the hollow portion on the appearance of the starry sky interior component.

[0010] In some embodiments of the first aspect, the area of ​​the first micropore array is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to better face the first micropore array, preventing the fabric layer surrounding the first micropore array from blocking the light-emitting surface of the light-emitting element.

[0011] In some embodiments of the first aspect, the diameter of the first micropores is less than or equal to 0.03 mm. With this configuration, the first micropore array can prevent some smaller debris from entering the first micropores while ensuring normal light transmission, thereby ensuring the light output effect of the light-emitting element.

[0012] In some embodiments of the first aspect, the fabric layer includes a first surface disposed proximate to the light source and a second surface disposed distal to the light source; the hollow portion includes a second light-transmitting hole and a second micropore array, the second light-transmitting hole being a blind hole disposed on the first surface, the second micropore array disposed on the bottom wall of the second light-transmitting hole, the second micropore array including a plurality of second micropores disposed throughout the second surface, the second micropores having a diameter less than or equal to 0.1 mm. This arrangement helps reduce light loss of light emitted by the light-emitting element when passing through the hollow portion, and can also better prevent larger objects from contacting and colliding with the light-emitting element, thereby better protecting the light-emitting element.

[0013] In some embodiments of the first aspect, the thickness d of the fabric layer and the depth h of the second light-transmitting hole satisfy the following relationship: h = (1 / 2 to 2 / 3) d. This configuration prevents the fabric layer from having excessively low structural strength and reduces light loss when light emitted by the light-emitting element passes through the hollow portion.

[0014] In some embodiments of the first aspect, the area of ​​the second light-transmitting hole is larger than the area of ​​the light-emitting surface. This arrangement allows the light-emitting surface of the light-emitting element to better face the hollow portion, preventing the fabric layer surrounding the hollow portion from blocking the light-emitting surface of the light-emitting element.

[0015] In some embodiments of the first aspect, the diameter of the second micropores is less than or equal to 0.03 mm. In this manner, the second micropore array can prevent smaller debris from entering the second micropores while ensuring normal light transmission, thereby ensuring the light output effect of the light-emitting element.

[0016] In some embodiments of the first aspect, the fabric layer is a natural leather layer or a suede layer. In this way, when the hollow portion is provided on the fabric layer, the fabric layer is not likely to crack, thereby facilitating the provision of the hollow portion.

[0017] In some embodiments of the first aspect, the light-emitting element extends into the hollow portion, which is conducive to improving the intensity of light emitted by the light-emitting element after passing through the hollow portion.

[0018] In some embodiments of the first aspect, the diameter of the light emitting surface of the light emitting element ranges from 0.15 mm to 2 mm. This configuration can prevent the light emitted by the light emitting element from being too glaring or too dim, thereby facilitating a better lighting effect of the starry sky interior.

[0019] In some embodiments of the first aspect, the starry sky interior decoration piece further includes a light-shielding layer, which is laminated on a side of the light source away from the fabric layer. This configuration allows the starry sky interior decoration piece to have a light-shielding effect, allowing the starry sky interior decoration piece to be used as a sunshade on a vehicle ceiling having a skylight.

[0020] In a second aspect, an embodiment of the present application provides a vehicle compartment ceiling, comprising a ceiling body, and the starry sky interior decoration component described in the first aspect, wherein the starry sky interior decoration component and the ceiling body are stacked.

[0021] The beneficial effects of the vehicle ceiling belt in the embodiment of the present application are the same as the beneficial effects of the starry sky interior decoration parts in the first aspect, and will not be repeated here.

[0022] In the third aspect, an embodiment of the present application provides a car ceiling, comprising a ceiling body, a first scroll, a first driving device and the starry sky interior component described in the first aspect; the ceiling body has a skylight, the first scroll is rotatably arranged at the edge of the skylight, the starry sky interior component is connected to the first scroll, the first driving device is connected to the first scroll, and is used to drive the first scroll to rotate, so that the starry sky interior component is gradually wound around the first scroll to open the skylight.

[0023] The beneficial effects of the vehicle ceiling belt in the embodiment of the present application are the same as the beneficial effects of the starry sky interior decoration parts in the first aspect, and will not be repeated here.

[0024] In some embodiments of the third aspect, the carriage ceiling further includes a second reel, a transmission belt, and a second drive device, wherein the second reel and the first reel are rotatably disposed at the edges of opposite sides of the skylight, one end of the transmission belt is wound around the first reel, and the other end of the transmission belt is wound around the second reel, one end of the starry sky interior decoration is connected to the transmission belt, and the other end of the starry sky interior decoration is connected to the first reel; the second drive device is connected to the second reel and is used to drive the second reel to rotate, so that the transmission belt drives the starry sky interior decoration to gradually separate from the first reel to close the skylight. With this arrangement, the speed at which the starry sky interior decoration opens and closes the skylight can be well controlled, thereby avoiding damage to the starry sky interior decoration caused by the starry sky interior decoration opening and closing the skylight too quickly.

[0025] In fourth aspect, an embodiment of the present application provides a vehicle comprising a carriage and wheels arranged at the bottom of the carriage, the carriage comprising a carriage bottom wall, carriage side walls, and the carriage roof described in the second aspect or the third aspect, the carriage side walls being connected between the carriage roof and the carriage bottom wall, and the starry sky interior decoration of the carriage ceiling being arranged on the inner side of the ceiling body.

[0026] The beneficial effects of the vehicle belt in the embodiment of the present application are the same as the beneficial effects of the starry sky interior decoration parts in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] With the growing demand for personalized vehicles, the vehicle modification market is booming, and vehicle ceilings featuring starry sky interiors have emerged. These decorative components, installed on vehicle ceilings, create a starry sky-like visual effect by arranging numerous small light sources. These components reflect people's pursuit of a romantic and unique cabin environment. Designing these components to enhance the user experience has become a key topic within the vehicle industry.

[0047] like Figure 1 As shown, Figure 1 The figure is a schematic diagram of the structure of a starry sky interior decoration in the related art. The starry sky interior decoration comprises a light source 01 and a decorative part body 02. The decorative part body 02 comprises a plastic base plate 021 and an inner fabric layer 022 stacked on the inner side of the plastic base plate 021. The light source 01 comprises a light source body 011 and an optical fiber 012. The light source body 011 is arranged on the outer side of the decorative part body 02 (i.e., Figure 1 The upper side of the decorative part body 02), the outer end of the optical fiber 012 (ie Figure 1 The upper end of the optical fiber 012 is connected to the light source body 011, and the inner end of the optical fiber 012 (i.e. Figure 1 The lower end of the decorative element is inserted into the decorative element body 02 and is flush with the surface of the inner fabric layer 022.

[0048] Light from the light source 011 is transmitted through optical fibers 012. Because optical fibers 012 are very thin, they appear as tiny dots of light on the decorative element 02, resembling stars. By controlling parameters like the color, brightness, and flashing frequency of the light source 011, various starry night effects can be simulated, ranging from static starry skies to dynamic effects like shooting stars.

[0049] The manufacturing process of the starry sky interior decoration is as follows: after the decoration body 02 is manufactured, the optical fiber 012 is passed through the decoration body 02 from the through hole on the decoration body 02, and the optical fiber 012 is on the inner side of the decoration body 02 (i.e. Figure 1 A certain amount of length is left on the lower side of the decorative body 02. The optical fiber 012 on the outside of the decorative body 02 is connected to the light source body 011. The optical fiber 012 protruding from the inside of the decorative body 02 is then trimmed so that the end face of the optical fiber 012 is flush with the surface of the inner fabric layer 022.

[0050] This kind of starry sky interior decoration part in the related art needs to trim the optical fiber 012 protruding from the inner side of the decorative part body 02 during the production process, which easily leads to the problem of uneven trimming, so that the trimmed end face of the optical fiber 012 feels prickly to the touch, which can easily cause harm to the user.

[0051] In order to solve the problem that the trimmed end face of optical fiber 03 feels prickly, Figure 2 As shown, the related technology provides another starry sky interior part, Figure 1 The difference of Zhongxingkong interior parts is: Figure 2 An enlarged portion 0121 is provided at the inner end of the optical fiber 012 of the starry sky interior decoration part, and the enlarged portion 0121 is in contact with the surface of the inner fabric layer 022.

[0052] By providing the enlarged portion 0121, when installing the optical fiber 012, the enlarged portion 0121 acts as a limiter, and the optical fiber 012 can be directly tightened from the outside of the decorative part body 02 so that the enlarged portion 0121 abuts against the surface of the internal fabric layer 022. In this way, there is no need to trim the optical fiber 012, thereby avoiding the problem of uneven trimming.

[0053] However, the expanded portion 0121 is exposed on the inside of the decorative body 02, making it susceptible to collisions with other objects, causing damage to the expanded portion 0121, thus increasing the repair cost of the starry sky interior decoration. Furthermore, since multiple optical fibers 012 are connected to the same light source body 011, it is impossible to individually control the light output of each light point on the decorative body 02 (i.e., the expanded portion 0121 of the optical fiber 012), thus affecting the luminous effect of the starry sky interior decoration.

[0054] To this end, the embodiments of the present application provide a starry sky interior, a car ceiling and a vehicle, by arranging an array of light-emitting elements on a bearing layer to form a light source, and at the same time arranging a fabric layer on the light-emitting side of the light source, and providing a hollow portion on the fabric layer at the position corresponding to the light-emitting element. In this way, while ensuring the normal light emission of the light source, the light-emitting element is prevented from being damaged by bumps. At the same time, each light-emitting element (i.e., light spot) can be controlled separately, which is beneficial to improving the luminous effect of the starry sky interior.

[0055] The technical solutions in some embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0056] Figure 3 Schematic diagram of the structure of the starry sky interior decoration part 100 in the first embodiment of the present application. Figure 3 As shown, the starry sky interior decoration part 100 includes a light source 1 and a fabric layer 2. The light source 1 includes a carrier layer 11 and a light emitting element array 12 disposed on the carrier layer 11. The light emitting element array 12 includes a plurality of light emitting elements 121. The light emitting surface 1211 of the light emitting element 121 faces the first side of the carrier layer 11 (i.e., the light emitting side of the light source 1, such as Figure 3 The lower side of the middle bearing layer 11). Wherein, Figure 3 As shown, the light emitting element 121 may be an LED (light emitting diode), such as a Mini-LED. Of course, the light emitting element 121 is not limited thereto, and the light emitting element 121 may also be other electroluminescent devices.

[0057] The fabric layer 2 is stacked on the first side of the carrier layer 11. The fabric layer 2 has a hollow portion 21 at a position corresponding to the light emitting element 121. The hollow portion 21 allows light emitted by the light emitting element 121 to pass through. Figure 3As shown, an adhesive layer 4 (e.g., a glue layer) may be provided between the fabric layer 2 and the carrier layer 11 to bond the fabric layer 2 and the carrier layer 11 together. Of course, the fabric layer 2 and the carrier layer 11 are not limited to being bonded together. The fabric layer 2 and the carrier layer 11 may also be connected together by means of a snap connection, a screw connection, or the like.

[0058] The starry sky interior decoration piece 100 in the embodiment of the present application is constructed by laminating a fabric layer 2 on the light-emitting side of the light source 1. The fabric layer 2 has a hollow portion 21 at the position corresponding to the light-emitting element 121. In this way, the light emitted by the light-emitting element 121 can pass through the fabric layer 2 through the hollow portion 21. This ensures that the starry sky interior decoration piece 100 can emit light normally, eliminating the need for optical fibers to guide the light source 1. This simplifies the structure of the starry sky interior decoration piece 100 and reduces the cost of the starry sky interior decoration piece 100. At the same time, the fabric layer 2 is arranged on the first side of the carrier layer 11 to cover and protect the light source 1, preventing the light-emitting element 121 of the light source 1 from being directly exposed outside the surface of the fabric layer 2. This protects the light-emitting element 121 from being damaged by bumps, which helps reduce the maintenance cost of the light source 1. In addition, each light-emitting element 121 (i.e., light point) in the light-emitting element array 12 is an independent light-emitting unit, and the light-emitting effect (such as light color, light brightness, and flashing frequency) of the light-emitting element 121 can be individually controlled, thereby improving the light-emitting effect of the starry sky interior decoration piece 100.

[0059] In order to make the light emitting surface 1211 of the light emitting element 121 better face the hollow portion 21, in some embodiments, such as Figure 3 As shown, the hollow portion 21 is a first light-transmitting hole set through the fabric layer 2, and the area of ​​the first light-transmitting hole is larger than the area of ​​the light-emitting surface 1211. With this arrangement, during the process of laminating the fabric layer 2 and the light source 1, the first light-transmitting hole with a larger area can better absorb the alignment tolerance between the light-emitting element 121 and the hollow portion 21, so that the light-emitting surface 1211 of the light-emitting element 121 is better aligned with the hollow portion 21, avoiding the fabric layer 2 around the hollow portion 21 from blocking the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the luminous effect of the starry sky interior component 100.

[0060] In some embodiments, as Figure 3 As shown, the fabric layer 2 is a fabric layer (e.g., a woven fabric layer), and the hollow portion 21 is a structural hole of the fabric layer 2. By fully utilizing the structural holes of the fabric layer 2 as the hollow portion 21, there is no need to additionally form the hollow portion 21 on the fabric layer 2, simplifying the manufacturing process and thus helping to reduce the manufacturing cost of the starry sky interior decoration component 100.

[0061] The structural pores of the fabric layer 2 refer to gaps or holes formed in the fabric layer, and the gaps or holes may be generated due to the fabric structure or the arrangement of the weaving threads.

[0062] In order to make the starry sky interior decoration part 100 have a better luminous effect, in some embodiments, such as Figure 3 and Figure 4 As shown, Figure 4 for Figure 3 In the bottom view of the starry sky interior decoration component 100 at the hollow portion 21, the diameter D of the light emitting surface 1211 of the light emitting element 121 ranges from 0.15mm to 2mm. This arrangement can prevent the diameter D of the light emitting surface 1211 from being too large or too small. If the diameter D of the light emitting surface 1211 is too large, the light emitted will be glaring, affecting the luminous effect of the starry sky interior decoration component 100; if the diameter D of the light emitting surface 1211 is too small, the light emitted will be dim, also affecting the luminous effect of the starry sky interior decoration component 100. Research has found that when the diameter D of the light emitting surface 1211 ranges from 0.15mm to 2mm, the light emitted by the light emitting element 121 can be prevented from being glaring or dim, which is conducive to making the starry sky interior decoration component 100 have a better luminous effect.

[0063] Furthermore, when the diameter D of the light emitting surface 1211 is in the range of 0.3 mm to 1 mm, it can better prevent the light emitted by the light emitting element 121 from being too glaring or too dark, thereby helping the starry sky interior decoration component 100 to have a better lighting effect.

[0064] The shape of the light emitting surface 1211 is not unique, for example Figure 4 As shown, the light emitting surface 1211 may be square, but is not limited thereto, and the shape of the light emitting surface 1211 may also be circular or other polygonal, such as a triangle, a pentagon, or a hexagon.

[0065] It should be understood that for a circular light-emitting surface 1211, the diameter of the light-emitting surface 1211 is the most intuitive description of its size; for a non-circular light-emitting surface 1211, such as a square or rectangular light-emitting surface 1211, the "diameter" is an equivalent diameter, which is usually determined based on some equivalent rule of the area or physical size of the light-emitting surface 1211. For example, for a square light-emitting surface 1211, its equivalent diameter can be the diagonal length of the light-emitting surface 1211, or the diameter of the light-emitting surface 1211 after being equivalent to a circle based on its area; or it can be the diameter of the circumcircle of the light-emitting surface 1211.

[0066] In some embodiments, as Figure 3 As shown, the light source 1 has a connection interface 13 , and the connection interface 13 is used to connect to a power supply line.

[0067] Figure 5 This is a structural diagram of the starry sky interior component 100 in the second embodiment of the present application. Figure 5 Starry sky interior 100 and Figure 3The main differences among the Starry Sky Interior Parts 100 are: Figure 5 Starry sky interior parts 100 in Figure 3 A light-shielding layer 3 is added to the starry sky interior decoration part 100, as described below:

[0068] like Figure 5 As shown, the starry sky interior decoration part 100 further includes a light-shielding layer 3, which is stacked on the side of the light source 1 away from the fabric layer 2. By providing the light-shielding layer 3, the starry sky interior decoration part 100 can have a light-shielding effect, so that the starry sky interior decoration part 100 can be used on the ceiling of a vehicle with a skylight to serve as a sunshade.

[0069] In some embodiments, as Figure 5 As shown, the light-shielding layer 3, the fabric layer 2, and the light source 1 are all flexible layers. With such a configuration, the starry sky interior decoration component 100 can be wound on a reel and used as a roller blind. Figure 5 As shown, the light shielding layer 3 can be a bottom woven fabric layer. In this way, the bottom woven fabric layer can play a buffering role and eliminate the noise when the starry sky interior decoration piece 100 is wound on the reel.

[0070] Of course, the light-shielding layer 3 is not limited to being a bottom woven fabric layer, and the light-shielding layer 3 may also be a film layer structure made of other light-shielding materials.

[0071] Figure 6 This is a structural diagram of the starry sky interior decoration component 100 in the third embodiment of the present application. Figure 7 for Figure 6 A partial enlarged view of the starry sky interior decoration part 100 at the hollow part 21, Figure 8 for Figure 6 A bottom view of the starry sky interior component 100 at the hollow portion 21. Figures 6 to 8 Starry sky interior 100 and Figure 3 The main difference between the starry sky interior decoration part 100 and the starry sky interior decoration part 100 is that the structure of the hollow part 21 is different, as described below:

[0072] like Figure 6 and Figure 7 As shown, the hollow portion 21 is a first micropore array, which includes a plurality of first micropores 211 provided through the fabric layer 2, and the diameter of the first micropores 211 is less than or equal to 0.1 mm. By setting the hollow portion 21 as the first micropore array, due to the smaller diameter of the first micropores 211 in the first micropore array, the first micropore array can better prevent some larger objects from contacting and colliding with the light-emitting element 121 while ensuring normal light transmission, thereby better protecting the light-emitting element 121 and preventing damage to the light-emitting element 121. In addition, setting the hollow portion 21 as the first micropore array can reduce the impact of the hollow portion 21 on the appearance of the starry sky interior 100, making the starry sky interior 100 more beautiful.

[0073] The bonding process of the fabric layer 2 and the light source 1 of the starry sky interior component 100 is as follows: the adhesive layer 4 is covered on the fabric layer 2, and laser holes are punched at positions of the fabric layer 2 corresponding to the light-emitting elements 121 to form a first micropore array, and then the fabric layer 2 and the light source 1 are aligned and bonded together through a vacuum bonding process.

[0074] The diameter of the first micropores 211 should not be set too large. If the diameter of the first micropores 211 is set too large, small debris (such as dust) can easily enter the first micropores 211 and affect the light emission of the light-emitting element 121. Research has found that when the diameter of the first micropores 211 is less than or equal to 0.03 mm, the first micropore array can prevent small debris from entering the first micropores 211 while ensuring normal light transmission, thereby ensuring the light emission of the light-emitting element 121.

[0075] In order to make the light emitting surface 1211 of the light emitting element 121 better face the first microhole array, in some embodiments, such as Figure 6 and Figure 8 As shown, the area of ​​the first micropore array is larger than the area of ​​the light-emitting surface 1211. With this arrangement, during the bonding process between the fabric layer 2 and the light source 1, the larger first micropore array can better absorb the alignment tolerance between the light-emitting element 121 and the first micropore array, allowing the light-emitting surface 1211 of the light-emitting element 121 to better align with the first micropore array. This prevents the fabric layer 2 surrounding the first micropore array from blocking the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the luminous effect of the light-emitting element 121.

[0076] It should be understood that the area of ​​the hole array refers to the size of the planar area occupied by the entire array containing all the holes, which includes the area occupied by the holes themselves and the area of ​​the spacing between the holes. For regularly arranged holes, such as a rectangular array, assume that there are n holes in each row and m holes in each column, the diameter of the hole is d1, the horizontal spacing between adjacent holes is x (that is, the size of the spacing area between adjacent holes in the horizontal direction), and the vertical spacing is y (that is, the size of the spacing area between adjacent holes in the vertical direction). Then the length of the hole array L = (n-1)x + nd1, the width W = (m-1)y + md1, and the area of ​​the hole array A = LW. For example Figure 8As shown, each row of the first microhole array has five first microholes 211, the diameter of the first microholes 211 is 0.1 mm, the horizontal spacing is 0.05 mm, and the vertical spacing is 0.05 mm. Then n = 5, m = 4, d1 = 0.1 mm, x = y = 0.05 mm. Calculation shows that the length L of the first microhole array is (5-1) × 0.05 + 5 × 0.1 = 0.7 mm; the width W is (4-1) × 0.05 + 4 × 0.1 = 0.55 mm; and the area A is 0.7 × 0.55 = 0.385 mm. 2 .

[0077] In some embodiments, as Figure 6 and Figure 7 As shown, the fabric layer 2 is a natural leather layer or a suede layer. In this way, when the hollow portion 21 is provided on the fabric layer 2, the fabric layer 2 is not easy to crack, thereby facilitating the provision of the hollow portion 21.

[0078] Natural leather is a material layer obtained from animal hides through a series of physical and chemical processing. Its primary component is collagen fibers, which form naturally during the animal's growth process. After processing, these fibers become a leather material with unique properties. Natural leather layers can be pigskin, sheepskin, or cowhide leather, and are not specifically limited here.

[0079] The suede layer is a synthetic material that mimics the look and feel of natural suede. It is a type of artificial leather, mainly used to replace natural suede, and is widely used in clothing, footwear, home furnishings, and automotive interiors. The main components of the suede layer are polyurethane (PU) and fiber components. Polyurethane is the most important component of the suede layer. Through special processing technology, polyurethane can form a surface with a suede effect, providing leather-like flexibility and wear resistance. In addition, polyurethane materials have good chemical stability and a certain tolerance to some common chemicals (such as detergents, mild acid and alkali solutions, etc.), which makes suede materials more convenient in daily use and cleaning. The fiber component can increase the strength and three-dimensional effect of the material.

[0080] Figure 9 This is a structural diagram of the starry sky interior component 100 in the fourth embodiment of the present application. Figure 9 Starry sky interior 100 and Figure 3 The main difference between the starry sky interior decoration part 100 and the starry sky interior decoration part 100 is that the structure of the hollow part 21 is different, as described below:

[0081] like Figure 9As shown, the fabric layer 2 includes a first surface 2a arranged close to the light source 1, and a second surface 2b arranged away from the light source 1; the hollow portion 21 includes a second light-transmitting hole 212 and a second micropore array 213, the second light-transmitting hole 212 is a blind hole and is arranged on the first surface 2a, the second micropore array 213 is arranged on the bottom wall of the second light-transmitting hole 212, the second micropore array 213 includes a plurality of second micropores 2131 arranged through the second surface 2b, and the diameter of the second micropore 2131 is less than or equal to 0.1 mm.

[0082] By configuring the hollow portion 21 as a combination of a light-transmitting hole and the second micropore array 213, the depth of the second micropores 2131 in the second micropore array can be reduced, thereby reducing light loss when light emitted by the light-emitting element 121 passes through the hollow portion 21, thereby ensuring the luminous effect of the starry sky interior 100. Furthermore, the second micropore array 213 is located on the second surface 2b, which can better prevent larger objects from contacting and colliding with the light-emitting element 121, thereby better protecting the light-emitting element 121 and preventing damage to the light-emitting element 121.

[0083] The bonding process of the fabric layer 2 and the light source 1 of the starry sky interior component 100 is as follows: the adhesive layer 4 is covered on the fabric layer 2, and a laser hole is punched at the position of the fabric layer 2 corresponding to the light-emitting element 121 to form a second light-transmitting hole 212; then the size of the laser spot is adjusted to perform micro-hole laser engraving to form a second micro-hole array 213, and then the fabric layer 2 and the light source 1 are aligned and bonded together through a vacuum bonding process.

[0084] In some embodiments, as Figure 9 As shown, the thickness d of the fabric layer 2 and the hole depth h of the second light-transmitting hole 212 satisfy: h = (1 / 2 ~ 2 / 3) d. This setting can prevent the hole depth h of the second light-transmitting hole 212 from being too large or too small. If the hole depth h of the second light-transmitting hole 212 is too large, the structural strength of the fabric layer 2 is reduced, and it is easy to be damaged by external forces; if the hole depth h of the second light-transmitting hole 212 is too small, the hole depth of the second micropore 2131 is large, which increases the light loss of the light emitted by the light-emitting element 121 when passing through the hollow portion 21. By making the hole depth h of the second light-transmitting hole 212 satisfy: h = (1 / 2 ~ 2 / 3) d, this not only avoids the structural strength of the fabric layer 2 from being too low, but also reduces the light loss of the light emitted by the light-emitting element 121 when passing through the hollow portion 21, which is conducive to ensuring the lighting effect of the starry sky interior 100.

[0085] In some embodiments, as Figure 9As shown, the area of ​​the second light-transmitting hole 212 is larger than the area of ​​the light-emitting surface 1211. With this arrangement, during the bonding process between the fabric layer 2 and the light source 1, the second light-transmitting hole 212 with a larger area can better absorb the alignment tolerance between the light-emitting element 121 and the hollow portion 21, so that the light-emitting surface 1211 of the light-emitting element 121 is better aligned with the hollow portion 21, and the fabric layer 2 around the hollow portion 21 is prevented from blocking the light-emitting surface 1211 of the light-emitting element 121, thereby ensuring the luminous effect of the starry sky interior component 100.

[0086] In some embodiments, the diameter of the second micropores 2131 is less than or equal to 0.03 mm. In this way, the second micropore array 213 can prevent some small debris from entering the second micropores 2131 while ensuring normal light transmission, thereby ensuring the light emitting effect of the light emitting element 121.

[0087] In some embodiments, as Figure 9 As shown, the fabric layer 2 is a natural leather layer or a suede layer. In this way, when the hollow portion 21 is provided on the fabric layer 2, the fabric layer 2 is not easy to crack, thereby facilitating the provision of the hollow portion 21.

[0088] Figure 10 This is a structural diagram of the starry sky interior decoration component 100 in the fifth embodiment of the present application. Figure 10 Starry sky interior 100 and Figure 3 The main difference between the starry sky interior decoration 100 is that the positional relationship between the light emitting element 121 and the hollow portion 21 is different, as described below:

[0089] like Figure 10 As shown, the light-emitting element 121 extends into the hollow portion 21, for example, the light-emitting element 121 extends into the second light-transmitting hole 212. This arrangement can shorten the distance between the light-emitting surface 1211 of the light-emitting element 121 and the second micro-hole array 213, thereby facilitating the improvement of the intensity of the light emitted by the light-emitting element 121 after passing through the hollow portion 21, thereby facilitating the luminous effect of the starry sky interior 100.

[0090] The above is a structural description of the starry sky interior component 100 in the embodiment of the present application. The application scenarios of the starry sky interior component 100 are specifically introduced below.

Figure 11 As shown, the vehicle includes a carriage 1000 and wheels 2000 arranged at the bottom of the carriage 1000. The carriage 1000 includes a carriage bottom wall 1100, a carriage side wall 1200, and a carriage roof 1300. The carriage side wall 1200 is connected between the carriage roof 1300 and the carriage bottom wall 1100.

[0092] The vehicle may be a sports utility vehicle (SUV), a multi-purpose vehicle (MPV), a sedan, a motorhome, a van, a bus, a truck, etc., without specific limitation here.

[0093] Figure 12 This is a bottom view of the carriage roof 1300 in the first embodiment of the present application. Figure 13 for Figure 12 AA cross-sectional view of the carriage roof 1300. Figure 12 and Figure 13 As shown, the car ceiling 1300 includes a ceiling body 200 and a starry sky interior 100. The starry sky interior 100 is stacked with the ceiling body 200, and the starry sky interior 100 is arranged on the inner side of the ceiling body 200 (that is, the side of the ceiling body 200 close to the interior of the car 1000).

[0094] Among them, the ceiling body 200 can be a plastic plate, but it is not limited to this, and other materials can also be used according to actual conditions. The starry sky interior decoration part 100 includes a light source 1 and a fabric layer 2. The light source 1 includes a carrier layer 11, and a light-emitting element array 12 arranged on the carrier layer 11. The light-emitting element array 12 includes a plurality of light-emitting elements 121, and the light-emitting surface 1211 of the light-emitting element 121 faces the first side of the carrier layer 11; the fabric layer 2 is stacked on the first side of the carrier layer 11, and the fabric layer 2 has a hollow portion 21 at the position corresponding to the light-emitting element 121, and the hollow portion 21 can allow light emitted by the light-emitting element 121 to pass through. An adhesive layer 4 (such as a glue layer) can be provided between the fabric layer 2 and the carrier layer 11, and the adhesive layer 4 bonds the fabric layer 2 to the carrier layer 11. Among them, the specific structure of the hollow portion 21 can refer to the description in the previous text and will not be repeated here.

[0095] Figure 14 This is a bottom view of the carriage roof 1300 in the second embodiment of the present application. Figure 15 for Figure 14 BB sectional view of the carriage ceiling 1300. Figure 14 、 Figure 15 Middle carriage roof 1300 and Figure 12 、 Figure 13 The main differences of the middle carriage roof 1300 are: Figure 14 、 Figure 15 The middle compartment ceiling 1300 has a skylight 210. The starry sky interior decoration component 100 can be wound on a reel to open the skylight 210, as described below:

[0096] like Figure 14 and Figure 15As shown, the car ceiling 1300 includes a ceiling body 200, a first reel 310, a first driving device 320 and a starry sky interior decoration 100; the ceiling body 200 has a skylight 210, the first reel 310 can be rotatably arranged at the edge of the skylight 210, the first reel 310 extends along the width direction Y of the ceiling body 200, and a guide rail 410 is also provided at the edge of the skylight 210, and the guide rail 410 extends along the length direction X of the ceiling body 200, the first end of the starry sky interior decoration 100 is connected to the first reel 310, and the second end of the starry sky interior decoration 100 is connected to the slider 420, and the slider 420 is slidably connected to the guide rail 410.

[0097] The vehicle ceiling 1300 further includes an elastic component 430, which is used to apply an elastic force to the second end of the starry sky interior component 100 so as to move in a direction away from the first scroll 310, such as Figure 14 The elastic force shown in is directed to the left.

[0098] The first driving device 320 is connected to the first scroll 310 and is used to drive the first scroll 310 to rotate, so that the starry sky interior decoration 100 is gradually wound around the first scroll 310 to open the skylight 210; when the skylight 210 needs to be closed, the second end of the starry sky interior decoration 100 moves away from the first scroll 310 under the action of the elastic force of the elastic component 430, so that the starry sky interior decoration 100 gradually separates from the first scroll 310 to close the skylight 210.

[0099] Among them, such as Figure 15 As shown, the starry sky interior component 100 includes a light source 1, a fabric layer 2 and a light-shielding layer 3. The light source 1 includes a carrier layer 11, and a light-emitting element array 12 arranged on the carrier layer 11. The light-emitting element array 12 includes a plurality of light-emitting elements 121, and the light-emitting surface 1211 of the light-emitting element 121 faces the first side of the carrier layer 11; the fabric layer 2 is stacked on the first side of the carrier layer 11, and the fabric layer 2 has a hollow portion 21 at the position corresponding to the light-emitting element 121. The hollow portion 21 allows the light emitted by the light-emitting element 121 to pass through. The light-shielding layer 3 is stacked on the side of the light source 1 away from the fabric layer 2, that is, between the light source 1 and the ceiling body 200. An adhesive layer 4 (such as a glue layer) can be provided between the fabric layer 2 and the carrier layer 11, and the adhesive layer 4 bonds the fabric layer 2 and the carrier layer 11 together. The specific structure of the hollow portion 21 can refer to the description above and will not be repeated here.

[0100] In some embodiments, as Figure 14As shown, the elastic component 430 is a spring, one end of which is connected to the slider 420, and the other end of which is connected to the connecting block 440 on the guide rail 410. When the starry sky interior decoration 100 is gradually wound around the first reel 310, the spring is in a stretched state, thereby applying an elastic force to the second end of the starry sky interior decoration 100, which can move it away from the first reel 310.

[0101] In some embodiments, as Figure 14 As shown, the first driving device 320 is a motor.

[0102] In some embodiments, as Figure 14 and Figure 15 As shown, the skylight 210 is a glass layer embedded in the roof body 200 .

[0103] In some embodiments, as Figure 14 As shown, there are two guide rails 410, located at opposite edges of the skylight 210 along the width direction Y of the ceiling body 200. There are two sliders 420, both connected to the second end of the starry sky interior component 100, with each slider 420 slidably connected to a corresponding guide rail 410. This arrangement prevents the starry sky interior component 100 from tilting in the width direction Y of the ceiling body 200, thereby ensuring smoother movement during the opening and closing of the skylight 210.

[0104] Figure 16 This is a bottom view of the vehicle ceiling 1300 in the third embodiment of the present application when the skylight 210 is in a closed state. Figure 17 for Figure 16 The CC cross-sectional view of the carriage roof 1300 shown in FIG. Figure 18 This is a bottom view of the carriage roof 1300 in the third embodiment of the present application when the skylight 210 is in a half-open state. Figure 19 This is a bottom view of the vehicle ceiling 1300 in the third embodiment of the present application when the skylight 210 is in the open state. Figures 16 to 19 The carriage roof 1300 shown in FIG. Figure 14 、 Figure 15 The main differences of the carriage roof 1300 shown in FIG are: Figures 16 to 19 The starry sky interior decoration part 100 in the vehicle ceiling 1300 shown in FIG is driven by a belt transmission mechanism during the process of opening and closing the sunroof, as described in detail as follows:

[0105] like Figures 16 to 19 As shown, the carriage ceiling 1300 includes a ceiling body 200, a first reel 310, a first driving device 320, a second reel 330, a transmission belt 340, a second driving device 350 and a starry sky interior decoration component 100;

[0106] The ceiling body 200 has a skylight 210. The second reel 330 and the first reel 310 are rotatably disposed at the edges of the skylight 210 on opposite sides. One end of a transmission belt 340 is wound around the first reel 310, and the other end of the transmission belt 340 is wound around the second reel 330. One end of the starry sky interior decoration 100 is connected to the transmission belt 340, and the other end of the starry sky interior decoration 100 is connected to the first reel 310.

[0107] The first driving device 320 is connected to the first reel 310 and is used to drive the first reel 310 to rotate (for example Figure 17 The first reel 310 is driven to rotate clockwise), so that the starry sky interior decoration 100 is gradually wound around the first reel 310 to open the skylight 210. The second driving device 350 is connected to the second reel 330 and is used to drive the second reel 330 to rotate (for example Figure 17 The second reel 330 is driven to rotate counterclockwise), so that the transmission belt 340 drives the starry sky interior decoration component 100 to gradually separate from the first reel 310 to close the skylight 210.

[0108] By driving the starry sky interior part 100 to open and close the sunroof 210 through a belt transmission mechanism, the speed at which the starry sky interior part 100 opens and closes the sunroof 210 can be well controlled, thereby avoiding damage to the starry sky interior part 100 caused by the starry sky interior part 100 opening and closing the sunroof 210 too quickly.

[0109] The transmission belt 340 may be of various types. In some embodiments, the transmission belt 340 may be a V-belt, with V-grooves provided on the first reel 310 and the second reel 330 to cooperate with the V-belt. In other embodiments, the transmission belt 340 may be a synchronous belt (i.e., a toothed belt), with teeth and grooves provided on the first reel 310 and the second reel 330 to cooperate with the synchronous belt.

[0110] In some embodiments, as Figure 16 As shown, along the length direction X of the ceiling body 200, a first reel 310 and a second reel 330 are respectively disposed at opposite edges of the skylight 210. Both the first reel 310 and the second reel 330 extend along the width direction Y of the ceiling body 200. Two transmission belts 340 are respectively disposed at opposite edges of the skylight 210 along the width direction Y of the ceiling body 200. One end of each transmission belt 340 is wound around the end of the first reel 310, and the other end of each transmission belt 340 is wound around the end of the second reel 330. One end of the starry sky interior decoration member 100 is connected to both transmission belts 340. This arrangement prevents the starry sky interior decoration member 100 from deflecting in the width direction Y of the ceiling body 200, thereby ensuring smoother movement of the starry sky interior decoration member 100 during opening or closing of the skylight 210.

[0111] In some embodiments, as Figure 16 As shown, the starry sky interior decoration 100 can be connected to the transmission belt 340 through the connecting rod 450, the middle part of the connecting rod 450 (i.e., the part excluding the two ends) is fixedly connected to the starry sky interior decoration 100, and the first end of the connecting rod 450 ( Figure 16 The upper end of the connecting rod 450 is connected to one of the transmission belts 340, and the second end of the connecting rod 450 ( Figure 16 The lower end of the transmission belt 340 is connected to another transmission belt 340.

[0112] In some embodiments, the first driving device 320 and the second driving device 350 may both be motors.
